Just Ask Happy: Two-Layer Low-Speed PCBs


Reading time ( words)

In our latest survey, we have asked that our readers send in questions they might have for Happy Holden, and quite a few of them took us up on it! The questions that were posed run the gamut, covering technology, the worldwide electronics fabrication market, and everything in between. Enjoy.

If you would like to participate in this ongoing survey, please follow this link.

The following is today's question and Happy's answer:

Q: Why do many two-layer boards work in low-speed applications, signal integrity-wise?

A: Two-layer boards, properly designed, will even work in high-speed applications! Even a single-sided board will. If the signal rise times are slow, signal integrity does not enter in the solution.

Seven Tips for Your Next Stackup Design

02/01/2021 | Eric Bogatin, University of Colorado, Boulder
Rarely do we have the luxury of designing a board just for connectivity. When interconnects are not transparent, we must engineer them to reduce the noise they can generate. This is where design for signal integrity, power integrity and EMC—collectively high-speed digital engineering—are so important. Eric Bogatin offers seven tips for stackup design.
